Generally there are no consequences of this for you. If you build your
|
|
own software and it requires this formula, you'll need to add to your
|
|
build variables:
|
|
|
|
EOS
|
|
s << " LDFLAGS: -L#{opt_lib}\n" if lib.directory?
|
|
s << " CPPFLAGS: -I#{opt_include}\n" if include.directory?
|
|
end
|
|
s << "\n"
|
